o facilitate the packing of the,device for shipment and to preventdamage to the arms 26 and 27 when not attached to an enclosure, thesaidarms may be pivotally connected to the device in such a manner thatthey may be swung toward each other to occupy a position mdicated bydotted lines in Fig. 4,'thereby brin ing the arms well within, theextremities o the holder.

The pivoting of these arms also makes possible the mounting of thedevice in places where it might otherwise be impos sible, if the armswere rigid with respect to the body of the holder.

To remove the moisture from the air of a show case, show window, orother enclosure in which the device ma be used, the holder 5 may containa suitab e hygroscopic material, shown, in the present instance, as apair of moisture. attracting and absorbing elements 31 and 32 extendinglongitudinally of the holder and preferably so formed, in

cross-section, that when placed together, the occup substantially theentire space wit in the older.'

The moisture absorbing elements 31 and 32 may be bound together in unitform by any suitable means, such, for example, as

the wires 33 and 34 surrounding the ele-- ments adjacent their ends.

The w1res 33 and 34 also serve to space the moisture absorbin elementsaway from the bottom, sides and top of the holder, while the bolts 24and 25, in addition to securing the end walls in place, serve to spacethe elements away from the end walls, thereby reducing to a minimum thepoints of contact between the device and the surface of the moistureabsorbing elements.

It will be observed that by positioning the moisture absorbing elementsout of contact with the top, bottom and enclosing walls of the device,substantially the entire surface of the elements is exposed .to the airof the enclosure, thereby materially facilitating the removal ofmoisture there- .4 from.

To provide additional surface for the attraction of moisture from theair within an enclosure, the inner or abutting faces of the moistureabsorbing elements 31 and 32 may be provided with longitudinallyextending channels or grooves 35 and 36 respectively, which, when thesaid elements are secured together as shown in the drawings, form anopening through the central portion of the hygroscopic material topermit of the circulation of the air therethrough, thereby providing formore rapid removal of the moisture from the air of the enclosure.

When the hygrosco ic materialhas taken on its full capacity 0 moisturefrom the air of the enclosure, the-holder,.together with the moistureabsorbing elements contained therein may be removed and subjected to adehydrating process by heating or otherwise, to restore theirhygroscopic condition and thereafter may be again placed within anenclosure and used until they again become saturated with moisture fromthe air.

therein.

limited to the particular construction and arrangement shown in theillustrative device, but may be variously modified. Moreover, it is notindispensable that all the features of the invention be used conjointly,since the may be used to advantage in variously 'flerent combinationsand subcombinations'.

Having thus described .my invention, I claim:

1. An article of the class described comprising aholder or receptacleopen to circulation of air; means secured to'said holder for securingthe-same within an enclosure; and a moisture absorbing substance housedand confined within said holder and having its surface spaced therefrom.

2. An article of the class described comprising an elongated holder.open to the circulation of air; means mounted on said holder forsecuring the same within an 'enclosure; and a moisture absorbingsubstance open to the circulation of air housed and confined within saidholder in amanner to 'be free from contact therewith.

4. An article of the class described comprising a holder having aplurality of perorations through its side, bottom and end walls;reinforcui means extending lon tudinally of sai holder and around tiends thereof; and a plurality of arms connected to said holder formounting the latter within an enclosure.

5. An article of the class prising a holder having integral perforatedside wallsrand bottom; a remforcing strip extending along and connectingupper described com- 1 forcing strip and bottom of said edges of saidside walls; perforated end walls; reinfmcing rings around the ends ofsaid holder and having inwardly extending ears; means cooperable withsaid ears, reinholder for securing said end walls in place; a moistureabsorbing substance having an opening therethrough contained within saidholder; and a pair of arms pivoted to said means for supporting saidholder within an enclosure.

6. In combination, an enclosure; an elongated holder open to thecirculation of air within said enclosure; and elongated moistureabsorbing means contained within said holder for preventing condensationof moisture within said enclosure, said moisture absorbing means beingpositioned fwithin said holder in a manner to expose substantially itsentire surface to the air of the enclosure. a

' 7. An article of the class described comprising a holder open to thecirculation of air of an enclosure; moisture attracting and absorbingmeans conforming substantially to the form of said holder and mountedtherein; and means for positioning said moisture attracting andabsorbing means within said holder in a manner to present substantiallyits entire surface to contact with the air of an the moisture therefrom.

8. In combination a holder adapted to be mounted in an enclosue and opento the circula ion of air therein; a moisture absorbing substance Withinsaid holder and positioned with respect thereto in a manner to presentsubstantially its entire surface to the moisture laden air of theenclosure to .acilitate the removal of moisture thereenclosure forremoving from er for closure.

9. An article of the class described comprising a holder or receptacleopen to the circulation of air; means for securing said holder within anenclosure; a moisture absorbing substance contained within said holder;means associated with said substance for positioning the latter withrespect to the bottom, top and side walls of the holder; and meansassociated with the holder for positioning said substance with respectto the end wallsof said holder. 10. An article of the class describedcomprising a holder or receptacle open to the circulation of air; meansfor securing said holder within an enclosure; a moisture absorbingsubstance contained within said holder; means for positioning saidsubstance with respect to the bottom, side walls of the holder; andmeans for positioning said substance with respect to the end walls ofsaid holder.

11. An article of the class described comprising a'holder open to thecirculation of air; a moisture absorbing substance contop and tainedwithin said holder; and means for I positioning said substance laterallyand longitudinally with respect to said holder.

12. An article of the class described comprising a holder open to thecirculation of air; a moisture absorbing substance contained within saidholder; and means for spacing said substance with respect to saidholder.

In testimony whereof, I have signed my Q name to this specification.
